So i have a fluval sea c4 powerhead in my 90g. I also have an AC70 and an AC110 running with an ATI sponge filter #5. I was wondering where should i place the powerhead? The two filters are about 15" apart and hooked up at the back wall of the tank with the output obviously going forward.

Right now i have the PH on the top right hand corner with the flow pointing lengthwise and about 3.5" from the top

Why do you have a power head? Dead spots, surface agitation?

You want it blowing the bottom level thus stirring up debris so your ac's can take care of business w/ mechanical filtration! Preferably 6" above sub pointed toward the ac110!

Surface agitation is greatly achieved thru your 2x h.o.b so utilize your circulater!

if you're drawing from the bottom, I probably wouldn't add a powerhead. if your HOB inputs are halfway up the tank or higher, I'd probably run it along the back at the bottom to stir up what sinks below the intakes.
